MOBILE GENERATOR OUTFIT.

Specification of Letters Patent.

Patented June 7, 1921.

T o all whom it may concern; y

Be it known that I, HENRY S. BALDWIN,

a citizen of the United States, residing at Lynn, county of Essex, Stateof Massachusetts, have invented certain new and useful Improvements in`Mobile Generator Out fits, of which the following is a specification.

The present invention relates lto mobile generator outts andparticularly to an improved arrangement wherein a generator is combined'with the motor drive of an automobile vehicle in an improved mannerwhereby the engine of the motor car can be used to drive either Ythevehicle or the generator. 'By this arrangement the engine can be used todrive the vehicle to any desired place after which it may then be usedto operate the generator. Current from the generator may be used forvarious purposes. For example, it mayl be -used to operate a searchlightor other apparatus carried on the vehicle itself or it may be used tooperate apparatus off the vehicle.

The primary object of my invention is to provide an improved arrangementfor mounting the generator in the car and for connecting the engine toeither the generator or the vehicle transmission.

A further object is to provide an improved arrangement of speed governorJr`or controllin the lengine when itis connected to drive te generator.

For a consideration of what I believe'to be novel and my invention,attention is directed to the accompanying description and the claimsappended thereto. Y

In the drawing Figurel is a diagrammatic view of a portion of a mobilegenerator outit' embodying my invention, and Fig. v2 is a sectional planview of certain parts on a larger scale than Fig. 1.

Referring to the drawing, 5 indicates an.

internal combustion engine of a vehicle and 6 the usual carbureter fromwhich fuel is supplied to the engine. In the mixing tube 7 of thecarbureter is a throttle valve 8 which controls the admission ofexplosive mixture to the engine, and fixed to the spindle of the valveisan operating arm 9 which is connected by a link 10 to the centralportion of a floating lever 11. The upper end of floating lever 11 isconnected to one arm 12 of abell crank lever, the other arm 13 of whichhas a sleeve 14 onits end which slides on a rod 15 just below a collar16 which is fixed to rod 15. The lower end of rod 15 is fastened to anarm 17 carried by a bevel gear wheel 18 which meshes with a second bevelgear wheel 19 on the lower endo rod 20 to the upper end of whichtheusual hand control lever 21 is fastened Arm 12 of the bell crank lever1s connected by a link 22 to the accelerator pedal 23, and a spring 23ais connected to pedal 23 which spring acts to move valve 8 toward closedposition. The lower end of floating lever 11 is connected by a rod 24 tothe governor llever 25 of a speed governor 26.

With the above described arrangement ythe throttle valve 8 can beoperated by either hand lever 21, accelerator pedal 23 or speed governor26. When hand lever 21 is turned in an anti-clockwise direction, gearwheel 18 will be turned to move arm 17 downward thereby pulling downonrod 15 and moving bell crank lever comprising arms 12 and 13 in adirection to open. wider valve 8. At such times the floating lever 11pivots on the end of rod 24. During such a movement, accelerator pedal23 is moved downwardand spring 23a is put under tension. When hand lever21 is moved in the opposite direction spring 23a will move valve 8toward closed position. When accelerator pedal 23 is pushed down link 22turns bell crank lever comprising arms 12 and 13, which resultsin'floating lever 11 pivoting on the end of rod 24 and opening the valve8. At such times the sleeve 14 slides on rod 15 and away from abutment16. When the accelerator pedal 23 is released spring 23a returns it andthe valve to a position where sleeve 14 strikes stop 16. The foregoingwill be readily recognized as the usual arrangement of hand lloe'ilferand accelerator pedal for an automo- When the speed governor 26 isoperating itinoves the throttle valve 8 by means of governor lever 25,rod 24, ioating lever 11 and link 10. At such times the floating lever11 pivots on the end ofbell crank lever arm 12.

The engine crank shaft 27 is connected to a transmission shaft whichextends to the rear wheels 28 of the vehicle to drive the same throughthe usual gearing as indicated at 29. 30 indicates the gear shittinglever, 31 the steering wheel, and 32 the foot pedal which controls theregular 'clutch for connecting the engine 5 to the transmission shaft.Lever 30 operates the usual transmission which is contained in casing33.

The parts so -far described with the exception of the speed governor 26and its connection to the carbureter throttle valve 8 may be taken astypical of any automobile vehicle the detail structure and operation ofwhich is Well understood.

Now according to my' invention I provide a enerator, the armature ofwhich has a quill shaft and I mount the generator on the chassis of thevehicle with the transmission shaft of the vehicle extending through thequill shaft of the generator armature. In other Words, the generator isconcentric with the transmission shaft. I then provide a coupling meansby Which the engine may be connected to drive either the vehicle Wheelsor the generator. When driving the generator, the speed governorreferred to above takes control of the throttle valve of the engine tohold the speed constant.

35 indicates the generator armature mounted on a quill shaft 36, and 37indicates the generator field structure. The field structure 37 issuitably mounted on the chassis of the vehicle, and has suitablebearings 38 (one of which is shown in Fig. 2) for quill shaft 36.l Thetransmission shaft referred to above is made in two sections a forwardsection 39 and a rear section 40. The forward section 39 extends throughquill shaft-36 and terminates in a housing 41 which is bolted to thegenerator field structure. Bolted to housing 41 is a bearing housing 42in which is carried by ball bearings 43 a member 44 which forms theforward end of shaft section 40, being fastened thereto by a coupling45. Member 44 is bored out to provide a bearing seat 46 which earriesabearing 47 for the end of shaft section 39, and a fiange 48 havinginternal teeth 49. Fixed on the end of quill shaft 36 is a short sleeve50 having internal teeth 5l and external teeth 52. Splined on the end offorward shaft section 39 is a clutch member 53 having teeth 54 whichteeth when member 53 is slid rearward engage teeth 49, and when member53 is slid forward engage teeth 51. Clutch member 53 is moved by meansof a hand lever 55 the lower end of which is connected by a sliding rod56 to a yoke 57 which engages member 53. The enternal teeth 52 on sleeve50 mesh with a Worm wheel 58 which drives the spindle of speed governor26.`

When the vehicle is to be propelled by engine 5, hand lever 55 is movedto bring teeth 53 of clutch member A52 into engagement with teeth 49 onflange 48. The forward and rear sections of shaft 39 and 40 are thuscoupled together so the engine may drive the wheels of the vehicle. Thevehicle is then operated in the usual manner. At such times thegenerator armature 35 is not connected with shaft section 39. Now whenthe vehicle has been brought to a location where it is desired tooperate the generator, the vehicle is stopped, the gear shlfting lever30 being positioned to put the gearing in casing 33 at neutral. Theengine is throttled so as to be running at a moderate speed. The clutchmember 53 is then moved forward to move teeth 54 out of engagement withteeth 49 and into engagement with teeth 5l. This couples the forwardshaft section 39 to quill shaft 36 which means that engine 5 may now beconnected to generator armature 35. To effect this the regular clutch isreleased by clutch pedal 32 andlever 30 is moved to throw thetransmission gearing into operative position (preferably into high). Theregular clutch is then again engaged with the result thaty the engine isconnected through the transmission gearing to the generator armature.The engine now operates the generator to produce power, the speed of theengine being controlled by speed governor 26 operating on throttle valve8 in an obvious manner.

The above described arrangement has the advantages that it occupies aminimum amount of space, and can be applied to existing types ofautomobile vehicles with but slight modifications in structure and withbut slight addition of weight. Also it requires, in addition to theregular clutch, but a single clutch member which may be very simple instructure, and a single operating lever.

In accordance with the provisions of the Patent Statutes, I havedescribed the principle of operation of my invention, together with theapparatus which I now consider to represent the best embodiment thereof,but I desire to have it understood that the apparatus shown is onlyillustrative and thatI the invention can be carried out by other means.
